vPC Configuration Strong Recommendation and Key Notes
{"Image DocumentName": "vPC Configuration Strong Recommendation and Key Notes", "Image ImageDescription": "Always use different domain ID in double-sided vPC topology. Operations perspective, define vPC primary on the left Nexus and vPC secondary on the right Nexus (role priority) When configuring large number of VLANs in a vPC environment, use the range command (vlan x-z) vs. individually configuring one at a time. Create a dedicated VRF for the vPC peer-keepalive link (ie. vrf context PKAL) When building a vPC peer-link, follow these guidelines. Must have Peer-keepalive link up first; ensure the peer-link member ports are 10 Gig interfaces. Use a minimum of two 10 Gig ports (M1 up to 8 member ports & F1/F2 up to 16 member ports) Use at least two different line cards to increase high availability of peer-link. Use dedicated mode 10 Gig ports with M1 32 line card vs. shared mode ports. Split vPC and non-vPC VLANs on different interswitch port channels. Don\u2019t insert any device between vPC peers; a peer-link is a point-to-point link. Any vPC VLAN allowed on the vPC member port MUST be allowed on the vPC peer-link. Always perform VLAN pruning on vPC peer-link with allowed list of vPC VLAN; vPC VLAN must have been pruned on the vPC member port previously. If the M1 32 is used for both the vPC peer-link and L3 uplinks to L3 Core, use vPC object tracking feature. When building a vPC member port, follow these guidelines. The configuration of the vPC member port must match on both vPC peer devices. If there is a inconsistency, a VLAN or the entire port channel may suspend (depending on type-1 or type-2 consistency check for the vPC member port) Use the same vPC ID as port channel ID for ease of configuration, monitoring, and troubleshooting. With the M1 Series line card :: there can be up to 8 active ports bundled \u2013 resulting a 16-way port channel to be built for the whole vPC. With the F1/F2 Series line card :: there can be up to 16 active ports bundled \u2013 resulting a 32-way port channel to be built for the whole vPC. Do not mix different port types (M1, F1, F2) in the same vPC member port; this is not allowed by the software. Both sides of the vPC member ports must be of the same port type.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
